oh yea, about the bec... my first Habu likely died because the steering servo had jammed when the nose gear retracted on take off, and I was using rudder at the time to correct for cross wind.
When it jammed it had enough draw along with all the other servos, gear, flaps and wot throttle to create a power failure in the stock esc. Fan pulsed and rx reset at the worst possible time... during climb after takeoff.
I will never again take that chance, now I believe in external bec or rx battery packs.

Ive had to add 16.5 grams to the tail to counter the 5s 3300 lipo, this is with the listed cg point in the manual. The battery itself weighs 448 grams. The esc is in the duct. Once the motor and fan arrive I will have to re-evaluate this again but I wonder if Im ok for now with this weight and and stock motor?

What is new motor/fan and weight relative to stock? Have you done cutting in battery tray area at all?

So in which case I would have to remove the added weight in the tail cone and actually slide the 5s 3300 forward slightly... which is good news. I did trim a very small amount of foam from the battery bay to move the 5s 3/4" back towards the rx. Nothing from the canopy had to be removed.

Started working on the Habu 2. Going for a 5s setup. I know the CC 100 is a little overkill but will use it on other projects. It's a little big and heavy so not going to work up front. Does anyone have any placement ideas.? I could always test fit on the habu 1. It has seen a scalpel before, no worries there. Still looking for an edf unit and motor. Our grass field doesn't like small landing gear so it will be hand launched and belly flopped. The white is a good foundation for a paint job. Undecided on that too. This project will take some time I think.....

the CC 100 is almost twice the weight of the eflite 60 and the TP 5s 3300 lipo is around 65 gr more than eflite 4s 3200 248.2 KB · Views: 17

Here's some images showing ESC placement options. Personally, I'm a fan of the first one. The smooth side gets cooling air in the intake, but doesn't disrupt airflow (as opposed to having the finned side out), and so the fan gets smoother air. The finned side gets cooling air as well inside the triangle area. Plus it helps with the CG.
Another great spot would be in the tail. That requires longer wires and a capacitor though.

Thanks for the good info. The more options the better. I like the triangle in between the inlets.

I'm not new to EDF's had the originl habu. I love my Habu 2 although yet to fly it was wondering if it would be ok to run a 3s 35C 3200 until I master her just to keep her at a good speed until orientation and landing and take offs are mastered. Or will I have a tougher time since she will be underpowered? I'm just asking because I have several 3s 3200's.

Underpowered, the motor will just pulse like when the lv cut-off kicks in. You need more voltage. If the motor does run good, you will not have enough power to fly, most likely glide 10 feet and then drop. Use a 4s and just use full throttle to take off and then ease it back little. Just make sure you carry some speed in turns.

A 4S is need because the stock motor is only 3200 kv. It needs the higher voltage to spin the fan and provide sufficient thrust. 3s packs are used with 4300 or higher KV motors (which are typical of smaller, 64 mm EDFs).

5 s setup

I just installed flaps and gear and with a turnigy 5 s battery on board the cg is way off. To balance the cg is now at about 2 inches from leading edge. Is this normal and if not where's the best place to hot glue some weight. I hate adding more weight.
